Note that the lower end surface portion 42c of the opening / closing projection 42 may have any shape as long as it has a shape (vertical rib shape, mountain shape, etc.) that rises to the mountain-shaped protrusion 31 when the overcap C is rotated.

Next, usage modes and operational effects of this embodiment will be described.
The assembly operation of the container provided with the overcap according to the present embodiment is as follows. First, the middle stopper B2 is rotated around the hinge B3 with respect to the middle stopper B1 as shown in FIG. B2 is attached to the upper part of the middle plug B1, and the middle plug member B is set.

At that time, as shown in FIG. 1, the engagement protrusion 16 formed on the inner periphery of the outer cylinder 21 of the outlet plug B2 is connected to the engagement protrusion 16 formed on the mounting cylinder 13 of the stopper plug B1. It is fitted by engaging.
Further, as shown in FIG. 3, the outer peripheral surface 11a of the outer cylinder 11 of the plug B1 during mounting and the outer peripheral surface 21a of the outer cylinder 21 of the outlet plug B2 are flush with each other, and the respective lower mountain-shaped protrusions 15 are provided. The upper end step surface 15c and the lower end step surface 27c of the upper mountain-shaped protrusion 27 are joined together to form a mountain-shaped protrusion 31 in which the lower mountain step surface 15b and the upper mountain step surface 27b are gently continuous.

Since the middle plug member B of this embodiment is connected with the middle plug B1 and the middle middle plug B2 via the hinge B3, it can be molded with a single mold during production. Efficiency can be increased.
In addition, since the dispensing plug B2 and the mounting plug B1 are set as a set by the hinge B3, the working efficiency when both are set is improved.

Thereafter, the inner plug member B is plugged into the mouth tube portion 1 of the container body A filled with the contents.
In the plugging step, the mouth tube portion 1 of the container main body A is applied to the annular groove portion formed by the inner tube 12, the upper wall 10 and the outer tube 11 of the plug B1 during mounting, and the upper wall 20 of the plug B2 being poured out. By applying a pressing force from above, the engaging portion 14 of the outer cylinder 11 gets over and engages the engaging protrusion 4 of the mouth tube portion 1, and the mouth tube portion 1 is connected to the inner periphery and the inner periphery of the outer tube 11. The cylinder 12 is fitted by being sandwiched between the outer periphery of the cylinder 12 and the upper wall 10.

  Finally, the work is completed by covering the container main body A with the overcap C so as to cover the inner plug member B.

  In the crowning process using the overcap C, the opening / closing protrusions 42 of the overcap C are aligned above the bottom step portion 15d of the mountain-shaped protrusion 31 on the outer periphery of the inner plug member B, and the overcap C is placed in the container. The main body A is pushed down to fit the locking projection 44 of the mounting cylinder wall 41 and the neck ring 5, and the lower end portion of the outer peripheral wall 36 is brought into contact with the step portion 6 of the container main body A to be crowned.

  At the same time, the fitting portion 37 on the outer periphery of the insertion boss portion 38 of the overcap C fits over the fitting protrusion 29 on the inner periphery of the cylindrical wall 28 formed on the top of the plug body 25 of the dispensing plug B2. At the same time, as shown in FIG. 2A, the inner teeth 43 on the inner periphery of the sealing ring 39 enter the space without the outer teeth 30 on the outer periphery of the cylindrical wall 28.

In the crowning process, as shown in FIG. 1, the mountain-shaped protrusion 31 protruding from the outer peripheral surface of the inner plug member B and the opening / closing protrusion 42 formed inside the overcap C abut, and the inner plug member Since the overcap C is mounted with respect to B with a predetermined positional relationship, the inner periphery of the inner periphery of the sealing ring 39 can be provided in the space where the outer teeth 30 on the outer periphery of the cylindrical wall 28 of the plug body 25 in the dispensing tube 23 are absent. The tooth 43 can be set at a position where the tooth 43 enters, and the inner tooth 43 and the outer tooth 30 do not collide (interfere) and push the plug body 25 downward.
In addition, after the dispensing plug B2 is mounted on the top of the mounting plug B1, the plug body 25 of the discharging plug B2 has a lower end surface that contacts the upper end surface of the protrusion 18 of the flow rate adjusting plate B1b of the mounting plug B1. Since the lowering is prevented by contact, the plug body 25 can be prevented from being pushed downward and breaking the weakened portion 24.

  Further, as shown in FIGS. 1 and 7 (a), the tip of the lower end surface portion 42c of each open / close projection 42 of the overcap C contacts the bottom step portion 15d of the mountain-shaped projection 31 on the outer peripheral surface of the inner plug member B. By contacting, it is possible to prevent the overcap C from being pushed down further with respect to the inner plug member B and the container main body A.

  Further, the locking protrusion 44 of the mounting cylinder wall 41 of the overcap C gets over the outer edge of the neck ring 5 of the container main body A, and the upper part of the locking protrusion 44 and the lower edge of the neck ring 5 are engaged with each other. The cap C is prevented from coming off from the container body A.

In using the container provided with the overcap, first, the overcap C is grasped and rotated in any direction.
When the overcap C is rotated, as shown in FIG. 7B, the lower end surface portion 42c of each opening / closing projection 42 is lowered from the bottom step 15d of the mountain-shaped projection 31 on the outer periphery of the inner plug member B to the lower mountain step. By moving to the surface 15b, the opening / closing protrusion 42 is lifted upward along the inclination of the lower mountain step surface 15b, and the overcap C is lifted.
When the overcap C is lifted, the engagement between the outer edge of the neck ring 5 of the container main body A and the locking projection 44 of the mounting cylinder wall 41 of the overcap C is released.

  When the overcap C is further rotated, the lower end surface portion 42c of each opening / closing projection 42 is moved to the upper mountain step surface 27b of the mountain-shaped projection 31 on the outer peripheral surface of the inner plug member B, and the overcap C is removed from the container body A. Removed and opened.

Simultaneously with the rotation of the overcap C, the inner teeth 43 formed on the inner periphery of the sealing ring 39 collide with the outer teeth 30 formed on the outer periphery of the cylindrical wall 28 of the outlet plug B2 and are being poured out. When the plug body 25 of the plug B2 is rotated, the thinned weakened portion 24 is broken, and the plug body 25 is disconnected by detaching the plug body 25 from the plug B2 during pouring, and as shown in FIG. A spout is opened along the circumference.
At that time, the plug body 25 cut off from the dispensing plug B2 is held by the overcap C as it is by fitting the fitting boss portion 38 of the overcap C into the cylindrical wall 28.

  When the container of the present embodiment is opened, the stepped surface of the angled projection 31 of the inner plug member B and the stepped protrusion 42 of the overcap C abut on each other and the opening and closing projections 42 of the overcap C contact each other. Since C is lifted from the container body A, the overcap C can be easily removed from the container body A and the inner plug member B regardless of whether the overcap C is rotated clockwise or counterclockwise.

  In dispensing the contents, the container is tilted with the overcap C removed, and the contents are poured out from the dispensing cylinder 23 of the dispensing plug B2.

In the container of the present embodiment, when the content is a low-viscosity liquid such as Worcester sauce, as shown in FIG. 8, the content liquid in the container main body A is attached to the stopper B1 during mounting with respect to the inclination of the container. The rectifying wall 17 of the flow rate adjusting plate B1b is temporarily dammed up, flows into the inner cylinder 12 using the lower flow path hole 19 with which the liquid content of the rectifying wall 17 comes into contact as a flow path, and is poured out from the dispensing cylinder 23. .
Further, the upper flow passage hole 19 where the content liquid of the rectifying wall 17 does not come into contact becomes an air flow path, and air replacement with the inside and outside of the container main body A is performed, thereby preventing pulsation of the content liquid and stabilizing the content liquid. Then, it can flow into the inner cylinder 12.

  If the contents are liquid such as tonkatsu sauce, etc., the liquid flow rate will be slowed by the viscosity of the liquid, so even if the container is tilted too much, the content liquid will be poured out all at once. There is no end.

  The middle plug member B of the present embodiment is composed of a middle plug B1 and a middle plug B2 and is provided with a flow rate adjusting plate B1b on the middle plug B1 so that it is a liquid with a certain degree of viscosity such as a tonkatsu sauce. Even if the liquid is low in viscosity, such as Worcester sauce, it is possible to cope with one type of inner plug as an inner plug that does not tilt the container too much to pour out the content liquid at once.

After the contents are poured out, the container body A is covered with an overcap C so as to return the inclination of the container and cover the inner plug member B, and the lid is closed.
At that time, the lower end surface portion 42c of each opening / closing protrusion 42 of the overcap C abuts on any step surface of the mountain-shaped protrusion 31 on the outer peripheral surface of the inner plug member B.
For example, when the lower end surface portion 42c comes into contact with the upper mountain step surface 27b or the lower mountain step surface 15b of the mountain-shaped protrusion 31, there is a force for lowering the overcap C along the inclination of the upper mountain step surface 27b or the lower mountain step surface 15b. Working in either direction of rotation, the overcap C descends while rotating.
Finally, the lower end surface portion 42c of each opening / closing projection 42 finishes descending at a position where it contacts the bottom step portion 15d, and the upper portion of the locking projection 44 of the mounting cap wall 41 of the overcap C and the neck ring The lower part of the outer edge 5 is engaged, and the closing operation is completed.

  Further, the sealing ring 39 of the overcap C has an inner periphery of the dispensing cylinder 23 of the dispensing plug B2 in a state where the plug body 25 broken from the dispensing plug B2 is held by the fitting boss portion 38 on the inner periphery. To seal the inside of the container.

  In the closed state, the lower end surface portion 42c of each opening / closing protrusion 42 is always closed at a position where it abuts against the bottom step portion 15d, so that the overcap C can be quickly lifted when the lid is opened next time. .

  In this embodiment, the mounting plug B1 and the dispensing plug B2 are integrally formed via the hinge B3. However, the hinge B3 is eliminated, and the mounting plug B1 and the dispensing plug B2 are molded separately. It may be set at the time of assembly.

In the present embodiment, the mountain-shaped protrusions 31 provided on the outer peripheral surface of the inner plug member B are the lower mountain-shaped protrusion 15 protruding from the mounting plug B1 and the upper mountain-shaped protrusion protruding from the dispensing plug B2. 27, the mountain-shaped protrusion 31 only needs to be able to be lifted by rotating the overcap C. Therefore, the outer peripheral surface 11a of the mounting plug B1 or the outer periphery of the dispensing plug B2 You may make it project only on the surface 21a the mountain-shaped protrusion 31 which has the step surface which continues between the bottom step part and top step part formed in an up-down direction.
In addition, it is only necessary to push the overcap into the container body from above to close the cap, and to turn off the cap of the spouting plug by rotating the overcap when the cap is first opened. Any plugging mechanism may be used.

  The present invention closes a cylindrical overcap by pushing it into the container body from above, and in a container that opens by rotating the overcap, grips the overcap and rotates it in either direction. By moving the cap, the overcap can be easily and reliably lifted from the container main body and the inner stopper member and opened, and the stopper formed on the dispensing tube of the inner stopper member can be removed. Even if it is a liquid with a certain degree of viscosity or a liquid with a low viscosity, it can be used widely regardless of the contents because it can be handled with a single type of plug member.
